CURRENT S&T / RESEARCH - Effects of perfluoroalkyl acids on in ovo toxicity and gene expression in the domestic chicken (Gallus gallus domesticus)

  • Toxicogenomics – Use of in vitro (cell culture) and in ovo (egg injection) approaches to determine the effects of priority environmental contaminants (e.g., perfluorinated compounds) on gene expression in avian species
  • Identify novel mechanisms of action of priority chemicals (e.g., thyroid hormone disruption)
  • Use of molecular technique (e.g., microarray and PCR technologies) to identify novel mechanistic modes of action of perfluorinated compounds
